Test query execution time in laravel

问题

How to test in laravel/phpunit how long query took to execute?

Is it possible so that it does not depend on something else?

回答1:

The oldest way is the best one:

$start = microtime(true);
// Execute the query
$time = microtime(true) - $start;

回答2:

Since Laravel 5.2 listen has changed to only except one argument:

\DB::listen(function ($query) {
     // $query->sql
     // $query->bindings
     // $query->time
});

Docs: https://laravel.com/docs/5.2/database

回答3:

You could listen to executing query like this and log the result in storage/logs/laravel.log.

\DB::listen(function ($sql, $bindings, $time) {
    \Log::info($sql, $bindings, $time);
});

You could just use $time only, but I logged $sql, $bindings, $time for the completion.

You could put this inside your AppServiceProvider.

UPDATE:

In Laravel version > 5.5 this approach is documented in the doc as listening for query events ;)

You can use ddd($someVar) helper starting from Laravel 6.x.

There is Queries tab which describes each query executed until ddd()
